Well I don't really have a set number in mind, but I know that later on I am going to want to procharge the truck and didn't want it to be an inconvenience to have to replace the pistons just for that. But my friend just gave me the pistons out of his totaled LQ9 and they're after market forged, so I dont think I will have a problem!

 

Make sure you get all the specs on them to ensure if they are a overbore and also to find out what Compression ratio they will put you at.
